Cowboys beat writer Jon Machota predicts that Joseph Randle will have first crack at the RB1 job in Dallas:
Randle has an outstanding opportunity in front of him if he’s able to take advantage. He gets the nod over Darren McFadden because he’s been in the system, has more tread on his tires and had success last season when called upon. If Randle stays out of trouble off the field, he could be Dallas’ next 1,000-yard back.
On average, Darren McFadden is still going ahead of Randle in early drafts, but we believe that Randle is the better bet. He was highly effective (6.7 YPC) in 2014 and is reportedly showing more maturity after several off-the-field issues. He's not going to see a DeMarco Murray-type workload, but 225-250 carries is feasible if he wins the lead back job.
